Preturn: Defend Babylon better. There are MDI at the gates. Minor tweaks.
IBT: Nippur is attacked by an Aztec spear and is captured. It was defended by an injured MDI.
1465 AD: Still dealing with the mad rush of units. No advancing at the moment.
Get a leader which I will save for an army. There is land to build new towns.
IBT: Declare war with the Celts. Pike on mountain holds off a Longbow and 2 MDI.
1470 AD: Declare war with Egypt and the Mongols.
Build 3 towns to get another Army.
Get Chemistry Science to 90% (lux at 10%) to get Metallurgy and Mil Trad as fast as possible. I think we will want to connect the Saltpeter when we get Metallurgy for the Cannons.
On the war front, I still have an annoying stack of 8 MDI well within our territory, but otherwise we have cleared out units in our lands.
IBT: Koreans show up.
1475 AD: Attacked and Auto-razed Sapporo, a new Japanese town.
IBT: Lots of Koreans.
1480 AD: Get ready to attack Korean hordes.
I was playing around with the settings - this seemed a good way to look for enemy units - ctrl-shift-n with only borders and units displayed. Note you can tell where the towns are because the team disc isn't displayed.
IBT: Suprisingly Korea attacks our heavily guarded town when it has a path to easier cities. The battle weakens us so that the Romans also attack. It is really close with us losing a knight. All 3 Armies survive.
1485 AD: This time I encourage the Koreans to go for the town which I defend with even more armies.
IBT: Koreans attack. Unfortunately, they get lucky and two Armies are lost. The other three survive. The Korean Horde have very few offensive units left. I am not worried about defending ourselves on that front any longer. Didn't intend to have it cost us Armies though. We need more leaders...
1490 AD: We get two! leaders this turn. Well if you can't be good you can always be lucky. Up to Max leaders again.

arty:
Things look under control at the end of this turn. The Iroquois are coming in dribs and drabs, the Dutch didn't have strong units (only a few swiss pike), and the Koreans broke their back on the walls of South Fort.
IBT: Oop Here comes the main Iroquois fast unit attack force. About 17 knights are in view. I expect we will have a slow unit wave as well.
1495 AD: Bombard the Iroquois and kill a few with an Army. They will likely retreat so we can handle them in pieces.
1500 AD: Kill More iroquois. Build a town to the East to slow the Iroquois advance slightly. There is open road leading into our lands.
Notes:
I did not mention the town building I did, but I basically filled the razed areas on the map. I believe initially we had 64 cities - we now have 76 so 12 more cities.
At 76 cities we can use our next leader for an army (we have 18 with a max of 19).
So far there are 3 civs to the West and the rest are all East. I am guessing the lands to the West are much smaller. However, since we have such a good choke point there, I think we should expand East.
We probably should be building more settlers. Next player may want to set some towns on that.
We need more town defense especially in the south. Build some pike.
We have 12 native workers that can be merged.
It might be nice to rush the Galley in Valley Mills to go for the Babylons.
All the Galleys near Yallbert have been sunk by a single galley (even with us fortified). I have not been able to get troops to Evora
Note I gave all the towns starting with the word New a name that was unique (so we have no towns that start with the word New (just because)).
I have found it useful to know the order of the AI turns. You can determine who is going to block whom in some cases.
Here is the order for anyone who also finds this useful. Note that it lists only civs for which I have seen a unit. We have more civs than this on the diplo screen. Blue city names are the three western civs. These tend to crowd one another and sometimes retreat. There are a number of retreated Romans for example.
Of these civs, I only saw boats/boat landings from England and Babylon - they may be on a different land mass.
